Used as an intermediate in the synthesis of dyes and pigments, particularly in the production of azo dyes which are widely applied in the textile industry for coloring fabrics. Also serves in the preparation of certain functional materials such as electroactive compounds and organic semiconductors. Its derivatives can be found in some polymer systems where they contribute to enhanced thermal and oxidative stability. Additionally, it has been explored in research settings for the development of sensors and optoelectronic devices due to its aromatic and electron-donating characteristics.
